The third step is D. subtraction property of equality
Simplify both sides of the equation.
3(x+4)+2=2+5(x−4)
Simplify
3x+14=5x−18
Subtract 5x from both sides.
3x+14−5x=5x−18−5x
−2x+14=−18
Subtract 14 from both sides. <---- Step 3
−2x+14−14=−18−14
−2x=−32
Divide both sides by -2.
−2x/−2 = −32/−2
x=16
